Xantia Suspesion / Ride Height

[rusty]

Got stiff rear suspension even though I replaced all 3 rear spheres. (Mine is not a Hydractive model).

I have read the other topics and some will surely help and I will follow the guides written.

I'm just hoping that removing the LHM tank and cleaning the filters is a straight forward task! (So maybe someone would be so kind to tip me on this procedure!)

The thing with my suspension is as follows: even though all spheres are new, 1st when I switch off engine, car lowers a bit from the back immediately accompanied with a low moaning sound. When I drive off, the rear feel stiff, I usually lower fully and lift the ride hieght with the shifter fully and ride looks better when I set back to normal height! any ideas?

Last curious thing is that the internal lever of the ride height selector is not functioning properly.

Lower level is fine, normal ride height works fine, 2nd higher ride height is not functioning properly (it seems to go immediately to highest level.), and highest level on selector lookks normal. Any clues anyone?

Would really appriciate any help!

Cheers and take care!

Hi Stefan,

Welcome to the forum, The guru known as "Colin Hunter" is your best bet on how to remove the LHM tank. No doubt Colin will reply when he gets the chance. As for the moaning sound that seems to be a foible of the suspension! My old Xantia used to do the same, with no adverse affects. As far as I am aware there is no need to lower the suspension when turning the engine off, just leave it at "Normal"

I would check the level of the LHM fluid, the brass disc in the sight glass on top of the tank should be midway between the two lines. If it is above then invest in a turkey baster and use it to remove the excess fluid. Oh don`t forget to check the level with the suspension set to high and have the engine running! I know on mine when there was excessive fluid, the suspension felt stiff. Right thats enough from me, I just hope it is of some use to you. Somebody will probably come and post a different solution, but thats what we are here for is to help each other.

Cheers

Dave.

I would suspect that the plastic link rod on the rear height corrector may have become disconnected. If you are going to check this make sure the vehicle is supported on axle stands as with a crushed head you wont have need to worry about it any more!!

Hi Dave,

 

Cheers for your quick reply and warm welcome here!

 

All plastic linkages of the hright corretcors are fine, that's why it is puzzling me why one of the height selectable settings is not functioning! (2nd setting higher on interior height selection lever)

My car lowers a bit when I switch off engine, strange when I know that all spheres are new!

I am suspecting that I have a leak (I need to top up LHM monthly), and maybe the system is sucking up air from somewhere! May that's why when I drive in the morning, the rear feels stiff, but when I lower it and fully lift suspension, it feels better - I am assuming that with this, I am like bleeding/priming the system.

I've read a lot that cleaning the LHM tank filters improves a lot, so I'll wait until an explained procedure is posted and try it out!

 

Cheesr fo now, take care,

 

Stefan

Hi Stefan,

I think you may have sorted your problem out yourself! It certainly sounds like you have air in the system, you are correct in that when you raise and lower the suspension, or as Colin calls it "Citrobics", you are bleeding the system of air. As for the tank, I will let Colin explain that! Its not hard, just awkward getting the hoses at the top out.

Cheers for now

Dave.
